"I didn't have a drug overdose. I took some shitty antibiotics that a doctor gave me for a sinus infection and I had a reaction," Cyrus told the press.

The "We Can't Stop" singer said she's now feeling "better than ever," and that the experience taught her a lot about taking care of herself.

"I'm probably the only one on this tour who doesn't drink or smoke before a show, as I take this really seriously," Cyrus said. "It's almost like being an athlete being up here, because if someone was f--ked up, they definitely couldn't do my show."

Cyrus previously opened up about her hospitalization telling Ryan Seacrest, "It was so scary … I had basically been poisoning myself with something I didn’t know I was really scary allergic to. I was on this medicine for five days and everything was all good and on the sixth day, I just woke up … I couldn't breath and my skin -- everything -- was going insane."
